A binary stream cipher sequence with the length N possesses low autocorrelation distribution if and only if its charateristic set is a differenceset in the residue ring ZN.Many classical difference sets and almost difference sets are proved to be formed easily by a new method based on their corresponding almost difference sets and difference sets respectively.These classical difference sets and almost difference sets were discoved by computer searching and other tendious methods.
